Description

Kathodenisolator für Großgleichrichter Die Erfindung betrifft eine besondere Ausbildung der Isolation zwischen dem Vakuumgefäß und dem Kathodenbehälter bei Metalldampfgroßgleichrichtern, d. h. eine besondere Ausbildung des sogenannten Kathodenisolators.Cathode insulator for large rectifier The invention relates to a special design of the insulation between the vacuum vessel and the cathode container in the case of large metal vapor rectifiers, d. H. a special training of the so-called Cathode insulator.

Die bekannten Kathodenisolatoren bestehen aus Ringen aus Isoliermaterial, beispielsweise Porzellanringen. Auch sind bereits Kathodenisolatoren vorgeschlagen worden, die aus einzelnen Ringscheiben, Gummi und Eisen abwechselnd, hergestellt werden, wobei die Eisenteile durch die Gummischeiben voneinander isoliert werden. Die Porzellanisolatoren haben den Nachteil, daß sie bei Großgleichrichtern sehr hoher Leistung Ausmaße erhalten müssen, die ihre Herstellung erschweren und deren Zerstörung oder Beschädigung begünstigen.The known cathode insulators consist of rings made of insulating material, for example porcelain rings. Cathode insulators have also already been proposed made from individual ring disks, rubber and iron alternately the iron parts are isolated from each other by the rubber washers. The porcelain insulators have the disadvantage that they are very large in large rectifiers high performance must be given dimensions that complicate their manufacture and their Promote destruction or damage.

Erfindungsgemäß werden nun günstigere Verhältnisse für die Kathodenisolatoren geschaffen, wenn man den Porzellanring ans einzelnen Segmenten zusammensetzt und die Segmente in Taschen eines Gummiringes einbettet. Die Verwendung eines Gummiringes als abdichtendeUmhüllung eines aus Porzellan o. dgl. bestehenden, nicht in Segmente unterteilten Kathodenisolators ist an sich bekannt.According to the invention, the conditions for the cathode insulators are now more favorable created when you put the porcelain ring together on the individual segments and embeds the segments in pockets of a rubber ring. The use of a rubber ring as a sealing covering of a porcelain o. The like. Existing, not in segments divided cathode insulator is known per se.

In der Zeichnung sindAusführungsbeispiele dargestellt. Abb. i zeigt einen Schnitt durch den Isolator eines Großgleichrichters, Abb. 2 eine Draufsicht auf den Kathodenisolator, Abb. 3 eine Innenansicht des Gummiringes mitteilweisem Schnitt.Exemplary embodiments are shown in the drawing. Fig.i shows a section through the insulator of a large rectifier, Fig. 2 is a plan view on the cathode insulator, Fig. 3 an interior view of the rubber ring mitteilweisem Cut.

Zwischen dem Vakuumgefäß i und dem Kathodenbehälter2 befindet sich ein mitTaschen 3 versehener Gummiring q.. In die Taschen 3 sind Porzellanringsegmente 5 eingesetzt. Zum Schutz des Vakuums vor Verunreinigungen durch etwa vom Gummi abgegebene Gase oder Dämpfe dienen Vordichtungsringe 6 und 7. Die Porzellanringsegmente 5 greifen, wie Abb. 2 zeigt, mittels Stege 8 übereinander, so daß an diesen Stellen der Gummi des Isolierringes nicht mit dem Vakuum in Verbindung steht.Between the vacuum vessel i and the cathode container 2 is located a rubber ring with pockets 3 q .. In the pockets 3 are porcelain ring segments 5 used. To protect the vacuum from contamination by, for example, released from the rubber Gases or vapors are used for pre-sealing rings 6 and 7. The porcelain ring segments 5 grip, as Fig. 2 shows, by means of webs 8 one above the other, so that the rubber at these points of the insulating ring is not in contact with the vacuum.
